Calm Warrington's session catwalk technique is used on the world's top models and is taken from the catwalks of London, Paris, New York and Milan - a true insider secret. Callam blow dries his model and creates a finish with smooth cuticles using suitable products. He attends to root direction and the parting to suit his finished look. Callam uses hair extensions made of 100% human hair. The result is a long look with a full healthy sheen.
